St. Peter Basilica, The Vatican, June 22, 1969
This is a story not before told in one place.
Its parts have for decades resided in obscurity: in three paragraphs of the 1952 internal communications of a religious congregation; in sworn affidavits of people long since deceased; in the archived tomes of the Holy See.
Some accounts match, some differ.
Some are in Portuguese, some English. Some are reported in the weeks following, some from a vantage point of thirty years hence.
